Glass is a liquid.

A lot of this myth comes from poor glass making techniques from 200+ years ago that resulted in windows with uneven thicknesses.

They say no, but then they say it would flow 10 angstroms in 14 billion years. So the answer is technically yes but practically no.

If you get it hot enough..

I read recently that glass is five times stronger than steel, and its brittleness is because of impurities and flaws caused by the manufacturing process. With modern manufacturing techniques we can remove those and make glass the perfect construction material.

Jury's still out on that one, but I'll be interested to see where it goes.

Not saying it’s true. But technically you can make a prince Rupert drop that’s stronger than some steel

It probably depends on the definition of stronger. Concrete is stronger in compression. If weight ratios are used then glass could win due to being lighter.

I heard this one recently from the person leading a historical tour. I looked around and everyone in the group was just nodding like, "oh, how interesting!"

This one is kinda sorta true if liquid simply means not absolutely solid. It's kinda like tar, or gum; solid but somewhat malleable.
